[CVS Update of freesbie2 - M:2 A:0 R:0]

Log Message:
-----------
Now that unionfs transparent copymode works, use mtree only with /etc and
/root by default to recover permissions lost with the iso filesystem
conversion. /usr and /var don't need (by default) any permission recovery
because they're compressed ufs filesystems.

Any user can set UNION_DIRS env variable to list the directory to be
partitioned starting from / (e.g.: "etc tmp var usr") and UNION_DIRS_MTREE
variable to list which of those directories need permission recovery (e.g.:
"etc")
